I have been told that the 40 cal needs a buffer even if I use an a2 stock.  

Should I use the thicker one (5/8"? ) and how will it affect the function of the gun versus the thinner one(3/16")?

In short, the buffer is a needed addition on the MP5 40 unless you want to end up with the unwanted "reciever roller dents" I would just use a stock with a buffer built in such as the choate folders or any of the A3 retractable stocks. Here are a few suggestions to consider.

The Standard A2 stock that was installed on the gun from H&K was unbuffered. Just make sure you run the MP5 40/10mm spec recoil spring, use the correct locking piece and your fine

That is correct and EVERY SINGLE postie I have seen had those receiver dents in them from the high impulse ammo and NO buffer to absorb it. I do not know about you but I would not want my MP5 40 or 10mm gun to get trashed the first time I took it out.

The correct locking piece was probably not installed then for the ammo those guns were using. I've handled a Post 86 with almost 10K rounds through it with no receiver dents that came from a PD with an A2 Stock.
H&K would of put a buffer in the gun that needed it if they had problems when using the correct LP depending upon ammo and the correct recoil spring. The only stocks i've seen with buffers were installed later or a US made stock
